Referring to FIG. 1, a knitted component 10 suitable for several applications (eg, footwear, apparel, and industrial textiles) is shown. The knitting component 10 may be a single knitting program (such as a weft knitting program (for example, using a flat knitting machine with one, two or more needle beds or using a circular knitting machine), a warp knitting program, or any other suitable knitting program ) Is formed as an integral single-piece component. The process of forming the knitted component 10 may be a hybrid knitting process in which one or more materials forming the knitted component 10 are not woven. For example, one or more materials (eg, yarn or thread) of knitted component 10 may be inlaid. As used in this application, a yarn may contain a thread, and it is not intended to limit the creation to multi-filament materials. The process of forming the knitted component 10 can substantially form the knitted structure of the knitted component 10 without requiring a large number of post-knitting procedures or steps. Alternatively, two or more parts of the knitted component 10 may be separately formed as distinct integral one-piece elements, and then the respective elements may be attached. In all of the above cases, the resulting knitted component may have an integral knitted configuration.

The knitted component 10 may include at least a first layer 14 and a second layer 18. The first layer 14 and the second layer 18 may be formed on one or more needle beds of a knitting machine, such as a first needle bed and/or a second needle bed. When one or both of the first layer 14 and the second layer 18 are formed on more than one needle On the bed or when the first layer 14 and the second layer 18 are formed on different needle beds, the resulting knitted component 10 is a multi-needle bed knitted component. As used in this application, the first layer 14 may form a first surface 22 including a first plurality of knit loops, and the second layer 18 may form a first surface including a second plurality of knit loops Second surface 26. The first layer 14 may overlap at least a portion of the second layer 18, and the first layer 14 and the second layer 18 may be connected in one or more dimensions; however, the first layer 14 and the second layer 18 need not be connected. At least a portion of the first layer 14 may be freely separable from the second layer 18. In other words, the first layer 14 and the second layer 18 may have one or more portions with opposed surfaces, thereby allowing their portions to be freely separated from the second layer 18. That is, the first surface 22 may generally face a first direction, and the second surface 26 may generally face an opposite direction. Although the first layer 14 may be freely separable from the second layer 18 in a specific area, it need not be freely separable. For example, the knitting assembly 10 may include one or more knit stitches (e.g., stitches formed during the same knitting procedure and extending between a first needle bed and a second needle bed) . These interlayer drop needles may be formed by the same yarn(s) or a different yarn forming the first layer 14 and/or the second layer 18. In one example, at least one weft loop of the yarn may form part of both the first layer 14 and the second layer 18, for example, formed on both the first needle bed and the second needle bed including the first surface 22 A woven structure of the first plurality of knitted loops and the second plurality of loops on the second surface 26. For example, in an interlocking knitted structure or similar structure including one or more weft loops having loops formed on both a first needle bed and a second needle bed, each weft loop may form the first layer 14 and at least a portion of the second layer 18. Alternatively, different weft loops of the yarn may form the first layer 14 and the second layer 18, for example, a first weft loop may form a single-sided flat needle first layer on a first needle bed, and a second weft loop may A second layer of single-sided flat needles is formed on a second needle bed, wherein at least a portion of the first layer of single-sided flat needles can be separated from the second layer of single-sided flat needles (as shown in FIGS. 4A and 4B ). Knitted component 10 may include additional layers to, for example, add cushioning, protection, or for other advantages. In various applications The first layer 14 or the second layer 18 may correspond to at least part of an outer layer or an inner layer of a garment or industrial textile, an outer layer or an inner layer of an upper of an article of footwear, or other applications .

The first layer 14 and the second layer 18 may each include one or more materials that have been selected to impart advantageous properties to the knitted component 10. For example, the first layer 14 may eventually correspond to an outer layer of an article of footwear, such as when the article has been assembled and configured to accommodate the foot of a wearer, and thus may include a relatively inelastic first yarn The weft ring provides abrasion resistance, water resistance and/or durability. Suitable materials for the first layer 14 may include polyester yarns, such as having a maximum tensile strength of at least about 0.5 kg-f (eg, ranging from about 0.5 kg-f to about 3.0 kg-f) and at least about 150 Denny (eg, ranging from about 150 Denny to about 1,500 Denny) is a linear density polyester yarn. The first layer 14 may also be weather-resistant, for example, it may be formed of yarn with water-repellent and/or water-resistant properties or it may have a durable water-repellent finish.

The second layer 18 may eventually correspond to an inner layer of a footwear object, such as when the object has been assembled and configured to accommodate a wearer's foot, and thus the second layer 18 may include a relatively soft hand One or more weft loops of the yarn (for example, a yarn with a fleece finish), or otherwise provide the wearer with breathability and comfort. Additionally or alternatively, the second layer 18 may contain one or more elastic yarns to impart elasticity to the knitted component. The examples are non-limiting and are intended to illustrate the diversity of the first layer 14 and the second layer 18, which can be formed by (several) the same yarn or different yarns or a combination of one or the like to be separate layers as needed or as appropriate And/or different parts, regions or regions of the respective layers provide advantageous properties.

Still referring to FIG. 1 and also to the representative cross-sectional view of FIG. 2, the knitted component 10 may include one or more weft loops of yarn positioned between the first layer 14 and the second layer 18 to strengthen the knitted component and improve strength (Especially tensile strength), directional stretch resistance, shape in specific embodiments Into an attractive appearance, enhance penetration resistance and/or be used for other advantages. For example, the knitted component 10 includes a first plurality of weft loops 28, a second plurality of weft loops 29, and a third plurality of weft loops 30. It will be understood that FIG. 2 is representative; although the first layer 14 is shown separated from the second layer 18 to reveal a plurality of latitude circles 28 to 30, the first layer 14 need not be freely separable from the second layer 18 . The plurality of wefts 28 to 30 can be formed between the first layer 14 and the second layer 18 due to the same procedure for forming the first layer 14 and the second layer 18; in other words, the plurality of wefts 28 to 30 are the same and integrated The part of the woven component 10 formed.

The plurality of weft loops 28 to 30 may each include one or more yarns (including a high-density yarn) and may be formed by inserting one or more high-density yarns into the first layer 14 of the knitted component 10 and The second layer 18 is formed in the middle. In particular, the plurality of weft loops 28 to 30 may be formed at least in part by inlaid weft loops of high-density yarn. In this application, if a yarn is placed in front of loops of some yarns and behind loops of other yarns (for example, between loops formed on the first needle bed and the second needle bed), it may Be inlaid. For example, an inlaid first yarn can be placed in front of a loop of a second yarn held on a first needle bed, and behind a loop of a second yarn (or a third yarn) held on a second needle bed . As another example, an inlaid first yarn may be placed in front of a first layer 14 and behind a second layer 18; in these cases, the first layer 14 and the second layer 18 may be freely separable or may not be free Separate. Subsequently, one or more yarns held on the first needle bed and the second needle bed can loop with the additional weft loops of the yarn and/or be inserted into another needle bed, thus closing or fixing the inlaid yarn in the knitting assembly 10 and effectively integrate the inlaid yarn into the one-piece knitted structure of the knitted component 10. In this way, an inlaid yarn may have a portion that does not loop with each other of the other yarns of the braided component, that is, the inlaid yarn may have a portion that may appear to extend straight through at least a portion of the braided component 10. This can be done, for example, on a knitting machine with a combination feeder or an inlay feeder.

Exemplary inlaid yarns are shown in FIGS. 3A-3B. In FIG. 3A, knitted component 32 includes a first yarn 34 forming a plurality of inter-engaging loops defining a plurality of horizontal weft loops and vertical warp loops. An inlaid yarn 36 extends along one of the weft loops and alternates between (a) positioning behind the loop formed by the first yarn 34 and (b) positioning before the loop formed by the first yarn 34. Although the first yarn 34 forms each of the weft turns in this configuration, the additional yarn may form one or more of the weft turns or may form part of one or more of the weft turns. Another example of a suitable configuration of one of the portions of knitted component 32 is depicted in FIG. 3B. In this configuration, the knitted component 32 includes a first yarn 34 and a second yarn 38 that define a plurality of weft and warp loops. Like the configuration in FIG. 3A, the inlaid yarn 36 extends along one of the weft loops and is positioned behind (a) the loop formed by the yarns 34, 38 and (b) positioned in the loop formed by the yarns 34, 38 Alternate between the front of the circle.

Generally speaking, the weft loops of the plurality of weft loops of the high-density yarn may have an interval relationship. In one example, the plurality of inlaid weft circles may be closely spaced, and in other examples, the inlaid weft circles may be spaced relatively farther from each other. The plural inlay weft circles can be evenly spaced from each other or the interval can be changed, some of the inlay weft circles are closely spaced from the adjacent inlay weft circles, while other inlay weft circles are further apart from the adjacent inlay weft circles.

As used in this application, if two weft loops of a high-density yarn are separated by no more than ten weft loops of other yarns, they can be closely spaced. In some examples, adjacent weft loops inlaid with high-yarn yarns may be separated by no more than five, four, three, two, one, or zero weft loops of another yarn. For example, if a first weft loop is set in the middle of a loop of a first weft loop of a second yarn, a second weft loop of a high-density yarn is set in a loop of a second weft loop of a second yarn And the first weft and the second weft of the second yarn by one, two, three, four, five, six, seven, eight, nine or ten of the second yarn When the wefts are separated, the first and second wefts of the high-density yarn are closely spaced. As another example, if the first weft of the high-density yarn is inlaid on a second In the middle of the loop of the first weft of one of the yarns, the second weft of the high-density yarn is embedded between the loops of the second weft of one of the second yarns, and the first weft and the second of the second yarn The weft loops are adjacent (ie, not separated by any weft loops), then the first weft loop and the second weft loop of the high-density yarn are closely spaced (in fact, they are continuous).

The number of weft loops of high-density yarns can vary. For example, some embodiments may include one or more plural high-density yarns, each of which has at least two, three, four, five, six, seven, eight, nine of high-density yarns Ten, ten or more latitude circles. For example, the first plurality of high-density wefts 28 of FIGS. 1 to 2 includes more than ten wefts (including wefts 28a and 28b) of high-density yarns extending substantially upward through the knitting assembly 10. The second plurality of high-density latitude circles 29 contains less than ten latitude circles (including latitude circle 29a). Alternate embodiments may include more or less weft loops of high-density yarns. The larger number of weft loops of the high-density yarn can provide greater reinforcement for the knitted component, and can be positively related to the strength of the knitted component 10, and can also be approximately parallel to the weft loop of the high-density yarn with the knitted component 10 The direction of stretch resistance is related. Generally speaking, at least some of the wefts of the high-density yarn may be complete wefts, such as the wefts 28a, 28b of the first plurality of wefts 28, which extend from one of the first edges 46 of the knitted component 10 to a first Second edge 50. Other knitted components may include weft loops extending from a first edge to a second edge and other weft loops extending from the second edge to a third edge. Alternatively, at least some of the weft loops of the high-density yarn may be partial weft loops (ie, extend an intermediate distance across a portion of the knitting assembly 10 or to a third edge in other embodiments), such as a second plurality of weft loops Weft circle 29a of circle 29. A knitted component may include both complete weft loops and partial weft loops of high-density yarn. In addition, each weft loop of the high-density yarn may be formed by a continuous yarn (such as the weft loops 28a, 28b of the first plurality of weft loops 28 extending across at least a portion of the knitted component 10 in a serpentine or zigzag pattern) Or by different yarns and individual ends (such as the weft loops 30a, 30b of the third plurality of weft loops 30). In either case, one or more weft loops of high-density yarn Can extend beyond one or more edges of the braided component 10, such as weft loops 28a, 28b (which form a loop or hairpin-shaped bend, for example, to extend through the braided component two or more times in reverse in accordance with a pattern) And weft circles 30a, 30b.

Suitable high-density yarns may include yarns formed to have one-density yarns in the range of at least about 6 g-force/danny (eg, about 6 g-force/danny to 10 g-force/danny) Polyester and other compositions. For example, a polyester yarn having a linear density ranging from about 275 Denny to 325 Denny and a maximum tensile strength of at least 1,650 g-force may be suitable. To facilitate weaving, in some embodiments, each weft loop of the high-density yarn may have a maximum diameter of less than or equal to about 1.0 mm, for example, less than or equal to 0.9 mm, 0.8 mm, 0.7 mm, 0.6 mm, 0.5 mm or a smaller diameter. A 300-denier polyethylene terephthalate yarn suitable for high-density yarns with a maximum tensile strength of one of 1,800 g-force and therefore one of 6 g-force/danny. A single yarn or thread can be used for each weft of high-yarn yarn. Or, the weft loops of the high-density yarn may include a plurality of yarns or threads so that the weft loops of the high-density yarn have a greater maximum tensile strength and Danny and therefore higher intensities. Referring to FIG. 4A, the weft loop 52 of the high-density yarn extends between the first layer 54 and the second layer 56 and includes one single end of the high-density yarn, for example, 1,000 deniers with a maximum tensile strength of 6,000 g-force One end of high-end yarn. By comparison, FIG. 4B illustrates a single weft 52 of a high-density yarn, which includes four ends of the high-density yarn, for example, 300 deniers of high-density yarns, and four ends of 1,800 g-force yarns . Although FIGS. 4A to 4B are representative, in other embodiments, each weft loop of the high-density yarn may include two, three, four, five, six, ten or more of the high-density yarn Large number of yarns. The multiple ends of the high-density yarn can be twisted, braided, formed into a core/sheath relationship or otherwise combined together to form a weft loop of the high-density yarn. As yet another example, one of the weft loops of the high-density yarn can utilize the three ends of 275 denier yarns, where each yarn has a maximum tensile strength of one of 1,925 grams-force, thereby forming 825 deniers and 5,775 grams- The strongest anti-Zhang Qiang One of the weft loops of high degree yarn. As yet another example, one of the weft loops of high-density yarns can utilize the four ends of 300 denier yarns, each with a maximum tensile strength of 1,800 g-force, resulting in 1,200 denier and 7,200 g-force One of the weft loops of high-strength yarn with maximum tensile strength. In summary, each weft loop of high-density yarn (including all yarns used to form the weft loop) may have a linear density of at least about 750 denier (eg, at least 1,000 denier) and at least about 4,500 g-force (eg , At least 7,000 g-force) one of the maximum tensile strength.

In the alternative embodiment of FIG. 5A, a knitted component 58 includes a first layer 60, a second layer 62, a first plurality of weft loops 63 (e.g., weft loops 63a) of high-density yarns, and high-density yarns The second plurality of weft circles 64 (for example, weft circle 64a). The first layer 60 includes a first plurality of pores 66 (eg, pores 66a) and a second plurality of pores 68. The first plurality of pores 66 extend in a latitudinal direction, and as an example, each pore of the first plurality of pores 66 has one of the longest dimensions oriented in the latitudinal direction, as shown in the detail diagram of FIG. 5B. It will be appreciated that each pore of the first plurality of pores 66 may have other shapes, orientations, and sizes. At least one exposed portion of the at least one weft loop of the high-density yarn (for example, the exposed portion 67 of the weft loop 63a) is exposed through each aperture of the first plurality of apertures 66. If the high-density yarn has a different color and/or other different visual properties relative to one of the yarn(s) forming the first layer 60, the exposed portion of the high-density yarn can provide an aesthetic visual appearance. The exposed portion of the high-density yarn may be concave relative to a first surface 70 of the knitted component 58 (eg, it may correspond to one of the outermost or outer surfaces of the knitted component 58), or the exposed portion of the high-density yarn may be permeable One or more of the plurality of pores 66 are prominent.

As an example, the second plurality of apertures 68 form a pattern that extends diagonally relative to the first edge 72 and the second edge 74 of the knitted component 58. Each pore of the second plurality of pores 68 has an elongated shape extending in the direction of the weft circle; therefore, each pore has an orientation different from one of the overall second plurality of pores 68. Each of the second plurality of pores 68 may have other suitable The shape, orientation and size. Advantageously, the second plurality of apertures 68 can provide the high-density yarn in the direction (s) of the pattern when the weft loops of the high-density yarn actually extend in the other direction (ie, one weft circle direction) That is, a visual impression is extended diagonally in FIG. 5A. In other words, in FIG. 5A, the high-density yarns seem to extend diagonally, but each weft (eg, weft 64a) of the high-density yarn has a weft orientation that is not diagonal.

The above knitted components have a wide range of useful applications, including footwear, apparel, and industrial textiles. As a non-limiting example, FIG. 6 illustrates an article of footwear 78 including an upper 82 formed at least in part from a knitted component 86 as described above. The article of footwear 78 has a general configuration suitable for walking or running. The concepts associated with footwear (including upper 82 and knitted component 86) can also be applied to a variety of other sports footwear types, including but not limited to baseball shoes, basketball shoes, cross-training shoes, cycling shoes, football shoes, football shoes , Running shoes, tennis shoes and hiking boots. These concepts can also be applied to footwear types that are generally regarded as non-sports, including dress shoes, loafers, sandals and work boots. Therefore, the concepts disclosed in this article are applicable to a variety of footwear types. In the embodiment of FIG. 6, the upper 82 may generally provide a comfortable and firm coverage for the wearer's foot. Thus, upper 82 may define an interior cavity 90 to effectively receive a foot and secure it within object 78. In addition, an optional sole structure 94 can be fixed to a lower region of upper 82 and can extend between a wearer's foot and the ground to reduce ground reaction forces (ie, cushion the foot), provide traction, and enhance Stability and affect the movement of the feet.

For reference purposes, the object 78 can be roughly divided into three general regions along a longitudinal direction (heel to toe): a forefoot region 98, which includes a forefoot edge region 102 and a toe cuff 104; and a midfoot region 106 ; And a hind foot area 110, which includes a heel area 112. The forefoot region 98 (specifically the toe cap 104) may generally include portions of the upper 82 that may eventually cover (when incorporated into an article of footwear) the toes and the joints that connect the metatarsal and phalanx. 106 in the midfoot area It generally includes a portion corresponding to an arch area of the foot and may include a throat area 114. The hind foot region 110 (specifically heel region 112) may roughly correspond to the portion behind the foot, including the area covering the calcaneus (which includes a portion of the wearer's heel). In addition, in some embodiments, the hind foot area 110 may cover some or all of the wearer's foot ankle (malleoli) and talus (which includes a portion of the ankle). The rear foot area 110 may coincide with a collar area 118. Upper 82 may also include: a medial side 122 having a medial edge region 126 (including a medial edge); and a lateral side having a lateral edge region (including a lateral edge). Each of medial side 122 and lateral side may extend through each of forefoot region 98, midfoot region 106, and hindfoot region 110 and may correspond to the opposite side. More specifically, the outer side may correspond to an outer area of the foot (ie, the surface facing away from the other foot), and the inner side 122 may correspond to an inner area of the foot (ie, the surface facing the other foot) correspond. The forefoot region 98, the midfoot region 106, the hindfoot region 110, the medial side 122, and the lateral side are not intended to delineate precise areas of the upper 82 or knitted component 86, but are intended to represent general areas to assist in the discussion below.

In FIG. 6, the knitted component 86 of the object 78 includes an outer layer 146 and an inner layer 150 and a plurality of weft loops 158 (shown as dotted lines, for example, a high-density yarn formed between the outer layer 146 and the inner layer 150 158a, 158b). The plurality of weft loops 158 can advantageously strengthen the knitted component 86, for example, by increasing its strength and increasing the stretch resistance in a specific direction (such as the medial-lateral direction and/or a forefoot-rear foot direction), and improve Locking of the wearer's foot during sports activities requiring lateral cutting movement (eg, basketball and football). In the embodiment of FIG. 6, the multiple weft loops 158 (eg, 158a, 158b) of the high-density yarn extend substantially over the upper 82 on both the lateral and medial 122, extending from the hindfoot region 110 to the midfoot Area 106 to the forefoot area 98. In other embodiments, one or more multiple weft loops of high-density yarn (including one or more multiple weft loops of high-density yarn) may be present in one or more zones, regions, portions of the upper , Side or other positions, including those described above. Outer layer 146 and inner layer 150 may hide at least a portion of the plurality of weft loops 158 of the high-density yarn, but in other embodiments, the pores in the outer layer and the inner layer may expose a portion of the plurality of weft loops of the high-density yarn. In other embodiments, the outer layer may include one or more features in addition to the pores, for example, a protruding woven structure forming a pattern (e.g., elongated and parallel woven structures, etc., which may, for example, be in relation to the sole structure 94 Directionally (e.g., diagonally), recessed, etc. The multiple weft loops 158 of the high-yarn yarn can also interact with a fastening system 162. In particular, the aperture of the fastening system 162 may extend through the plurality of weft loops 158, thereby adding strength to the fastening system 162. In one example, a loop portion 170 of one of the high-density yarns may loop around one or more lace apertures 174 so that when a lace is fed through the aperture(s), it also extends through Loop formed by high-yield yarn.

Still referring to FIG. 6, the weft loop 158a of the high-density yarn extends from the inner edge zone 126 to a portion of the weft loop of the throat zone 114 in a medial-lateral orientation. By comparison, the weft loop 158b is a complete weft loop of high-density yarn extending from the outside to the inside 122 (ie, from the outside edge region to the inside edge region 126). In other embodiments, the weft loops of the high-density yarn may be present in one or more partial portions of the upper, for example, in the midfoot region 106, the forefoot region 98, and/or the hindfoot region 110. Likewise, in other embodiments, the weft loops of high-density yarns may have an orientation other than medial-lateral orientation. For example, the weft loops of the high-density yarn may be oriented in a direction where it is desired to increase the stretch resistance in the same direction (eg, a forefoot-rearfoot direction or a direction inclined to the sole structure 94).

FIGS. 7A-7B show an alternative footwear article 184 that includes an upper 188 combined with an optional sole structure 192, the upper 188 being formed at least in part from a knitted component 196 constructed as described above. The knitted component 196 includes an outer layer 200 and an inner layer 204 and a first plurality of weft loops 212 of high-density yarn formed between the outer layer 200 and the inner layer 204. the first A plurality of weft loops 212 are positioned in a midfoot zone 216 on an inner side 220, and a second plurality of weft loops 224 of a high-density yarn are positioned in a forefoot zone 226 spanning both the inner side 220 and an outer side 228 Among those. The positions and sizes of the first plurality of weft loops 212 and the second plurality of weft loops 224 are merely exemplary; other embodiments may include one having various sizes or at least partially occupying any one or more of the above-mentioned areas Multiple multiple high-yarns. The first plurality of weft loops 212 and the second plurality of weft loops 224 of the high-density yarn can form part of a first high-density area 232 and a second high-density area 236, namely, a partial area of the object 184 , Etc., each including a plurality of weft loops of high-density yarns and other structures for the benefit of reinforcement, increased strength and increased stretch resistance provided by high-density yarns. In other embodiments, more or less high-intensity zones may exist in the same or different positions as those shown in FIGS. 7A-7B.

In FIGS. 7A to 7B, the high-density yarn utilized in the first plurality of weft loops 212 has at least one visual property (e.g., reflective and/or different from the material(s) used to form the outer layer 200) A different color or texture). The first high-density region 232 includes a first plurality of pores 240 formed in the outer layer 200, which etc. extend diagonally with respect to the sole structure 192 on the inner side 220, and are aligned with the high-density yarn The first plurality of weft circles 212 overlap. Each of the first plurality of pores 240 has an inside-outside orientation. In other embodiments, one or more plurality of pores may extend in several directions or form several different patterns, and each pore may have several different individual orientations and several individual shapes. Each of the first plurality of pores 240 exposes a portion of at least one of the first plurality of wefts 212 of the wefts of the high-density yarn. Therefore, the exposed portion of the high-density yarn (which has at least one different visual property relative to the outer layer 200) is visible through the first plurality of pores 240. In other embodiments, the exposed portion of the high-yarn yarn may be recessed relative to a first surface of the outer layer (which may correspond to an outermost surface of the article of footwear). In addition, the first plurality of pores 240 can be in the inner-outer side of each weft loop of the high-density yarn in fact When extending upward, it provides a visual impression that the first plurality of weft loops 212 of the high-density yarn extend in a diagonal direction. This may be the result of the first plurality of pores 240 being formed in a substantially diagonal orientation as shown in FIG. 7A, where each successive pore exposes at least a portion of one or more weft loops of the high-density yarn. In other words, successive pores in a specific diagonal of one of the pores can expose a different weft of a high-density yarn.

The second high-density region 236 includes a second plurality of pores 244 formed in the outer layer 200 and positioned in the forefoot region 226, which wait together to form an "X" or diamond pattern and are second to the high-density yarn Plural weft circles 224 coincide. The pores are shown as oblong or elliptical, but can have a variety of shapes, orientations, and sizes as desired in other embodiments. Because each aperture of the second plurality of apertures 244 exposes a portion of at least one weft loop of the second plurality of weft loops 224 of the high-density yarn, the knitted component 196 can in fact have a high degree of highness of the second plurality of weft loops 224 Each of the weft loops of the yarn extends in a medial-lateral direction to provide a second plurality of weft loops 224 of the high-density yarn extending diagonally to form a visual impression of an "X" or diamond pattern. In other embodiments, different pore configurations in the outer layer and different visual properties of the outer layer and the portion of the high-density yarn exposed through one or more of the pores can produce a wide range of different patterns and visual effects.

FIG. 8 illustrates a knitting sequence that can be used to form a body knitting assembly as described above, such as through a weft knitting program (eg, using a flat knitting machine with one, two, or more needle beds). The non-limiting sequence of FIG. 8 is shown on a weft knitting machine having a first needle bed 252 and a second needle bed 256. The weaving sequence shows the formation of a plurality of weft loops of a first layer, an overlapping second layer and the high-density yarn 268 therebetween. The outer layer and the inner layer are at least partially formed by a first yarn 260 and a second yarn 264. Obviously, there is no need to use both the first yarn 260 and the second yarn 264, because a single yarn can form both the first layer and the second layer; but different yarns are shown to better convey high-density yarns The interval between 268 weft circles. Weaving process to form multiple wefts of high-density yarn Loops, thereby advantageously increasing the strength of the resulting knitted component and the stretch resistance in the weft loop direction. In addition, the non-limiting sequence of FIG. 8 includes forming a plurality of pores in the first layer to expose high-yarn 268.

In a first step 272, the machine forms a weft 276 of the first yarn 260 (which forms part of the first and second layers) on both the first needle bed 252 and the second needle bed 256, and executes Transfer 280 to form pores in the first layer. In preparation for the transfer 280, the weft loop 276 has not knitted any loops on the needles of the second needle bed 256 corresponding to the positions where the pores will be formed later in the first layer. Following the weft loop 276, the transfer 280 moves the knitting loop formed on the first needle bed 252 in the weft loop 276 to the second needle bed 256.

In a second step 284, a weft loop 288 of the high-density yarn 268 is embedded between the loops previously formed on the first needle bed 252 and the second needle bed 256 during the weft loop 276. As discussed above, weft loop 288 may include one or more ends of high-density yarn 268. After the second step 284, the first step 272 and the second step 284 may be repeated as appropriate to add more weft loops to the first and second layers and by inlaying additional weft loops of high-density yarn 268 Make the woven component bigger.

In a third step 292, the knitting machine knits three weft loops 296, 300, 304 of the second yarn 264 on the first needle bed 252 and the second needle bed 256, thereby making the knitting assembly larger. At the weft loop 296, the machine forms a tuck of the second yarn 264 on the first needle bed 252 at a position corresponding to the before-after transfer in the first step 272, thus in the second step 284 The inlaid weft loop 288 of the high-density yarn formed during this period is fixed in the knitted component.

After the third step 292, the first step 272 to the third step 292 may be repeated as necessary to make the knitted component larger and inlay additional weft loops of the high-density yarn 268. The position of the transfer and tuck can be changed to adjust the position of the pores formed in the first layer; alternatively, if the pores are not desired, the transfer and tuck can be exempted, but the tuck can advantageously fix the inlay of high-yarn yarn Latitude circle. Regardless, the resulting knitted component will include the first and second layers and the plural of high-density yarn 268 Inlaid weft circles. The weft loops of the high-density yarn 268 in FIG. 8 are closely spaced. This is because one of the weft loops of the high-density yarn 268 is inlaid on top of each of the weft loops of the first yarn 260. In this case, these The weft loops are separated only by the three weft loops of the second yarn 264. In other embodiments, the weft loops of high-density yarns may be more closely spaced, such as (continuously) inlaid after each weft loop. Alternatively, the weft loops of high-density yarns can be spaced to a greater degree without departing from the original creation, for example by up to four, five, six, seven, eight, nine or ten yarns Latitude circles are spaced apart. In other embodiments, the size of the pores may be larger to increase the exposed portion of the high-density yarn, for example by transferring the knitted loops of two, three or more consecutive needles from the first needle bed to The second needle bed.

Knitted components constructed as described above can impart many advantages to uppers, footwear, clothing, industrial textiles, and other applications. In particular, one or more weft loops of the high-density yarn can strengthen and increase the strength of the knitted component, especially in the direction parallel to and approximately parallel to the weft loops of the high-density yarn. This can be useful in footwear, where selective placement of these knitted components can improve directional stability. In addition, the weft loops of high-density yarns can increase the stretch resistance in parallel and approximately parallel to the weft loops of high-density yarns, for example, to improve the locking of the wearer's feet in an article of footwear advantage. In addition, when a first layer contains one or more pores thereby exposing a portion of the high-density yarn, the knitted component may have aesthetic visual properties; for example, a plurality of pores in the first layer may be formed to convey the high-density yarn A pattern of the appearance of the weft circle extending in a first direction, even if it actually extends in a second direction.

Although various embodiments of the creation have been described, the creation is not limited, except for the scope of the accompanying new patent application and its equivalents. In addition, the advantages described herein are not necessarily the only advantages of the creation, and it is not necessarily expected that each embodiment of the creation will achieve all the advantages described.
